About The Brand

A global study conducted across 30 countries in 2013–2016 finds that 45% of people are currently trying to lose weight[1]. However, while weight-loss efforts are increasing, there is no corresponding decrease in the obesity[2] trend globally. This is linked to the possibility that many people are trying to lose weight but are not pursuing it effectively. 

A pill becomes worth a try when calorie restriction and cardio workouts leave you tired and hungry. These pills make you feel more full so that you eat fewer calories, reduce the absorption of nutrients, take in fewer calories, or increase fat burning, making you burn more calories.

But repeatedly, most diet pills fail because they don’t work round the clock. This is not so much for daytime snacking as late-night snacking, which builds up undesirable and unhealthy fat in your various body storage parts.

What Is Phen24?

Phen24 is a 24-hour fat-burning, unique weight-loss pill[3] that helps eliminate excess fat and provides optimal weight. This weight loss capsule acts as a natural fat burner that helps increase your body’s metabolic rate by using effective weight-management techniques that suppress food intake and promote fat metabolism. 

Phen24 fat-burning supplement (formula) comprises two separate pills – one you take in the morning and the other just before bedtime (the Day Formula and the Night Formula). 

The two individual doses have distinct roles in your weight loss efforts. The daytime formula aims to give you more energy and improve your mental focus, while the nighttime formula aims to decrease stress levels to improve the sleep cycle while keeping the fat-burning mechanism on the go. The night formula is the ideal remedy for binge eaters who need help overcoming late-night snacking.

Does Phen24 Really Work?

Phen24 raises the body’s metabolic rate and prompts the thermogenesis process based on your explicit sleep and wake cycle. These two operations decide how quickly your body burns fat to enable swift, healthy weight loss. 

In addition, the supplement quashes your appetite to reduce food cravings. As a result, you can work in a calorie shortage mode and equally track a specific diet plan.

Phen24 Ingredients

Phen24 Daytime Capsules:

They raise your body’s metabolism to burn calories and help you lose weight faster. They also help repress your appetite and elevate your energy levels. The ingredients are:

  • Zinc – 15 mg
  • Iodine – 150 mcg
  • L-Phenylalanine – 70 mg
  • Guarana Extract – 100 mg
  • Cayenne Powder – 20 mg
  • Manganese – 2 mg
phen24 ingredients

Daytime Capsules Ingredients:

  • Zinc: Research points out that zinc can help stimulate your immune system and speed up fat loss by boosting the metabolism. It functions by enabling your body to absorb nutrients like iron and calcium. The daytime formula contains 15mg of zinc per serving, barely more than the daily advised dosage but still within safe limits, which is 40mg daily. 
  • Iodine: has been shown to play a paramount role in discouraging fat storage in the abdomen. According to Phen24, iodine is included in the daytime formula to facilitate thyroid function. 
  • L-Phenylalanine: helps you lose weight by enhancing your capacity to metabolize fats. Fatty acids join your liver through your small intestine. Once inside, fatty acids break down into smaller molecules called ketones. L-phenylalanine can be a good appetite suppressant. L-phenylalanine is an exceptional supplement for periodic fasting as it keeps you full for longer, easing hunger-induced fatigue. 
  • Guarana extract: Researchers believe that guarana work by raising energy expenditure. This means that guarana enhances how much energy your body burns at rest. It’s contained in Phen24’s daytime formula to support and lessen fatigue and improve athletic performance.
  • Cayenne powder: Research suggests that cayenne powder can help you burn more daily calories — up to 50-250 calories. The cayenne powder contains capsaicin, a compound that helps curb appetite. Capsaicin activates receptors in your stomach that inform your brain when you have had enough to eat. When you feel heavy, your brain transmits cues to your mouth, telling it to cease eating.
  • Manganese: Clinical studies have proven that manganese can help raise your metabolism and burn fat to build energy.
  • Copper: Research has shown that copper might be paramount for enabling people to drop and keep a healthy weight. The mineral is an integral part of our diet as it reinforces the immune system, helps with iron absorption, and converts sugar into energy. 
  • Caffeine: Scientific proof indicates that caffeine administers mood swings, elevates energy levels, and raises fat loss. Furthermore, caffeine can help enhance focus and promote thermogenesis, enhancing metabolism. 

Phen24 Nighttime Capsules

They promote healthy sleep and weight loss without interrupting your sleep. It is particularly formulated to help reduce cortisol levels at night, helping you feel calm while reducing cravings. The ingredients are:

  • Glucomannan – 1000 mg
  • Green Tea Extract – 40 mg
  • Chromium – 120 mcg
  • Ascorbic Acid – 80 mg (Vitamin C)
  • D-Biotin – 120 mcg
  • Molybdenum – 100 mcg
  • Griffonia Extract – 52 mg
  • Choline Bitarate – 40 mg
  • Hops (Humulus lupulus L.) Extract – 25 mg
  • Calcium D-Pantothenate – 10 mg
  • Pyridoxine HCl – 5 mg
  • Thiamine HCl – 4 mg

Nighttime Capsules Ingredients:

  • Glucomannan: is a dietary fiber that makes you feel fuller, making it an effective appetite suppressant. The ingredient is also considered to delay cholesterol and sugar absorption in the gut, enabling the body to manage sugar and lower cholesterol levels.
  • Green tea extract: Some studies suggest that drinking green tea can support weight loss by boosting thermogenesis, where your body generates heat. It causes your body to burn calories at rest.
  • Chromium: A study suggests chromium can help suppress appetite and decrease carbohydrate and sugar cravings.
  • Ascorbic acid: Some studies imply that drinking green tea may help weight loss also by increasing thermogenesis. The night formula contains 80 mg of ascorbic acid per serving.
  • D-biotin: When combined with chromium, biotin can help raise the resting metabolic rate and speed up weight loss.
  • Molybdenum: One study showed that people with molybdenum deficiency had higher levels of leptin, a hormone that controls appetite and body weight. Leptin levels heightened when subjects ate foods rich in protein or fat.
  • Griffonia extract: Saponin extracts from Griffonia have decreased food intake and promote weight loss. In fact, studies show that they may be effective in treating obesity.
  • Choline bitartrate: can help metabolize your body fat, which may help with weight loss.
  • Hops extract: is also known to increase metabolism and burn calories.
  • Calcium D-pantothenate: helps reduce total fat stored close to the abdomen particularly.
  • Pyridoxine HCL: One animal trial suggests that pyridoxine HCL can help decrease appetite. The night formula contains a small dose of 5 mg pyridoxine HCL per serving.
  • Thiamine HCL: Also known as vitamin B1, thiamine HCL can metabolize glucose and help your cells convert carbohydrates into energy. Inadequate vitamin B1 delays your metabolism and disrupts the weight loss operation.

How Does Phen24 Actually Work?

This supplement never stops working; they support weight or fat loss regardless of how many pounds you have added in the last couple of days, weeks, or months.
